I'm planning on getting a custom 2 1/2" cat back exhaust put on my 93 v6 4runner. i want a good performance muffler that will definately give a nice noticeable sound, but not sound like a coffee can honda civic exhaust. Just wondering if anyone has a muffler in mind that will fit my wants. Plus i was wondering if i should get a high flow cat or not( if it will make any differance). thanks

 

Dynomax! Everybody who has one loves it, I may be purchasing one soon.

 

I have a flowmaster 60 series. I like it because it isn't raspy, and it doesn't drone on the freeway. But when I step on the gas, I can hear it!!

 

I can't believe that no one has sent you over to listen to Corey's Exhaust Comapison page...

i got the dynomax super turbo muff from summit racing for around 50 bux shipped. i forget the part number. ill try to find it. it sounds awesome on my 93

 

i have a spintech that i got for 80$. The guy recommended it over flowmasters, but i havent had both so i cant make any comparisons. Ive been really happy with this muffler, great sound, and noticeable horsepower.

 

I have both a carsound hi flow cat and a "turbo" muffler with the 2.25" exhuast cat back. (The muffler i think is a dynomax.)

I think I actually lost power until the ECU reset, now it's about the same.....at least the 150 I paid for my exhaust was worth it for the sound. She sounds GREAT with a good growl.

I think you are going to notice a nasty loss going to the 2.5" instead of 2.25" or 2"

 

The dynomax ultra flow sounds great on my prerunner with the 3.4. Its got a quite note at idle and low rumble during acceleration, on the interstate you cant really hear it but when ya punch it its there in full force. Id recommend it to anyone with this motor.

 

Where did you guys purchase your mufflers? Are there muffler shops that
have Dynomax, Flowmaster, or MagnaFlow mufflers in stock ready to put on
or did you have to order the muffler yourself and then take it to a muffler
shop to weld on?

 

i bought my dynomax from summit racing..then just took it to a muffler shop and had them put it on.

on a side note..what part of atl are you from.?>

 

I bought mine at the shop the day they put it on. Their price was very close to catalog so instead of waiting I just bought it from them.

 

I was just wondering what size piping, muffler, and cats you guys are using. what will give the most perfomance and sound quality. thanks for all the info so far.

 

I didnt mess with the cat, and the stock pipe on my 01 was 2.5" for the 3.4, so I just kept with that size, I think 2.25 is recommended for 4 bangers and 2.5" for the smaller sixes.

 

2.25" for the 3.0 V6.

You will see below the 150 HP V6 runs best with 2.25".
The 3.4 V6 as stated runs best with 2.50" tubing.

 

I'm going to get the the low profile Spintech when I get mine, because it will provide the most amount of clearance for off-roading.

okay thanks everybody, i just ordered my muffler and cat. i got the dynomax high flow cat, and a dynomax super turbo muffler. i decided to go with the 2 1/4" set up after looking at the dynomax website and charts. thanks again

 

I think youll like the turbo, its louder than the ultra flow but not annoying.

 

does anybody besides downey make headers for 2nd generation 4runners. i was just wondering if there was any selection out there, or if thats all there is.

 

Actually, if you listen to the sound files on their website, the turbo dynomax
is much more muffled than the ultraflow (i.e. quieter). It isn't a straight
through design like the ultraflow and thus more restrictive. I would expect
that an engine without a turbo or SC would do better with the Turbo design
muffler, you need some backpressure to avoid loosing low end torque.

I'm about to put a Dynomax UltraFlow on my rig. There is a local muffler
shop that stocks them and everyone that has them seems to like them.
